Fiction and nonfiction are two distinct categories of written works. Fiction is a type of literature that is entirely made up and can include stories, novels, and plays. It is usually written in a creative style and often includes elements of fantasy or science fiction. Nonfiction, on the other hand, is based on facts and real events. It includes biographies, autobiographies, histories, scientific studies, and other forms of writing. Nonfiction is usually written in an informative or persuasive style and does not contain elements of fantasy or science fiction.
